Shadowing is hardly an arbitrary factor, and what you said was, and I quote:
For the record, Aura looks great where it counts (the top, which is what the increased height has made more prominent from further away), and Trump is probably one of the best looking buildings built in the core in recent times.
No one is complaining about Aura's height, and I don't think any of it's many detractors ever have. When they do complain about it's height, it's in relation to how such a poorly designed building is unfortunately going to be one of our tallest and most visible skyscrapers, but that's completely different from being opposed to it's height, or height in general.
Which is entirely besides the point, as what angus was responding to was your assertion that the top of the building is where it counts, which is absolutely not the case (though that's not to say the top of a tower is not important), rather, what's unequivocally more, and indeed most important, is the ground level, where the building interacts with pedestrians and the street. That is what truly matters most.
And to once again reiterate and make myself abundantly clear, no one is saying that the tower portion of a building should not be aesthetically pleasing or well designed, quite the contrary. Simply that if you think it's the most important aspect of a building, than you would be very mistaken.
For the record though, Aura fails quite splendidly on the ground level, and, whilst I'm not an architect, it's abysmal mediocrity and poor design and execution are incredibly disheartening
for such a prominent and tall tower. Were it designed by aA, Core, Raw, S+P, D+S, HP, Teeple, Wallman, [good] Quadrangle, or any of a number of other talented architects that I may be forgetting, I imagine you'd be hard pressed to find anyone complaining about Aura, for it's height or otherwise.
